In field experiments conducted to investigate into irrigation/rain induced chlorosis of winter crops in heavy textured coastal saline soil of West Bengal, it was observed that chlorosis of barley plants was associated with fall in redox potential and increase in available Fe and Mn in soil. There was a sharp rise in Fe and Mn content and decrease in P concentration of plant immediately after heavy irrigation] rain. Within 6 to 10 days following irrigation/rain, Fe and Mn content of plant was increased twofold. Application of large amount of well decomposed farmyard manure (40t/ha) and fertilizer P(l50 kg P2O5ha) and raking of soil after receding of standing water proved to be beneficial.
